Seed germination and seedling growth of Albizia lebbeck and and Leucaena leucocephala were significantly (p < 0.05) reduced at 500 and 700 ppm of lead and cadmium as compared to control. 700 ppm of Pb showed the highest reduction in seed germination and seedling growth of both species. Lowest reduction in different parameters of Albizia lebbeck and and Leucaena leucocephala were found at 500 ppm of Cd as compared to other treatments applied in this investigation. Percentage of tolerance was lowest at 700 ppm of lead than other treatments. L. leucocephala was comparatively more tolerant to Pb and Cd than A. lebbeck.
